Necromancers haven't really had any key skill changes for a long time so everything that was working then should work now, such as:
-Minion Masters and Bombers.
-Assassin's Promise to allow spamming of long recharge skills.
-Using Soul Reaping to pretend to be a Monk or Mesmer.
-etc...
Necromancers are the most versatile profession in the game, rivaled only the Ritualist, so you can easily find something effective for every situation, even with a restricted skill set.
